Exactly. Facebook doesn't need to raise money since it's the world's biggest social network platform. There are many people using Facebook, where the company earns money form their data and ads. Being a billion dollar company, gives them an advantage over other established players within the Blockchain industry. They could design a robust Blockchain network that could stand the test of time. Facebook's only concern into launching Libra for the world is the disapproval of worldwide governments and central banks. Considering that these entities are opposing the launch of Libra, it's hard to believe that it'll become a reality by 2020.

Even if Facebook manages to launch Libra somehow, it won't make any difference in our economy whatsoever. After all, Libra will be a stablecoin just like Tether. Cryptocurrencies like Bitcoin and Ethereum will continue to deliver as intended without any interruptions whatsoever. Libra's success or failure won't pose to be a threat to the very existence of cryptocurrencies worldwide. However, the ambitions of launching a global blockchain network by a company shows us how that Blockchain is the way of the future for mainstream finance. Either Facebook launches it own blockchain network, or another company will in the future. As long as the new global blockchain network gathers the approval of governments worldwide, it'll successfully launch without any interruptions whatsoever. Just my opinion
